Bryan Robson is proof Manchester United can make a miraculous comeback against Liverpool.

United legend Robson captained the side as they produced one of their great rallies to beat a Barcelona side including Diego Maradona in the old European Cup Winners’ Cup 32 years ago.

Captain Marvel scored twice in one of his finest displays for the club before Frank Stapleton netted at Old Trafford as they won 3-0 on the night and 3-2 on ­aggregate.

United have progressed four times in Europe after losing the first leg by two goals and Robson says Louis van Gaal’s side can overturn their 2-0 deficit against arch-rivals Liverpool at Old Trafford on Thursday night and reach the Europa League's last eight.

“It would be our greatest win over Liverpool if we could do it — and we did it against Barcelona, so it shows it is doable,” said the Red Devils legend.

“For me, that was the best atmosphere inside Old Trafford I’ve witnessed.

"It was a great night to come back against a top team like Barcelona and beat them 3-0.

“If the fans get right behind the team, players respond to that. Big players love a great atmosphere, especially on your home soil. If you get that atmosphere going and we get an early goal, then it can be done.”
